然後,對nasa開發的空間碎片演化模型evolve4 . 0進行研究,並將它的碎裂模型與建立sdem過程中所參考的碎裂模型進行比較,從爆炸子模型、面質比分佈子模型和速度分佈子模型幾個方面進行了詳細的對比,並在條件簡化的前提下給出初步的比較結果。2 ) the effects on waves conversion are stronger in rocks with dry fractures than that in rocks with water - filled fractures, and s - waves attenuate more rapidly in rocks with water - filled fractures. 3 ) the explosive point source which locates in anisotropic media can excites not only p - waves but also s - waves. 4 ) the properties of waves propagation were discussed and compared for several point sources with different source functions
結果表明: 1 )平行排列裂縫造成的各向異性使波前變寬; 2 )含乾裂縫巖石對波型轉化的影響比含充水裂縫巖石的大,橫波在含充水裂紋中傳播時衰減較快; 3 )當介質存在各向異性時,爆炸點源產生的波不僅有縱波,還有橫波; 4 )通過改變點源函數研究不同點源所產生波以及波型的轉換。The results at normal temperature have shown that klc of high polymer bonded explosive are very low comparing to metals and some high polymer materials, thus the ability of pbxs to resist crack expanding is very poor, and once some cracks occur inner a structural part of pbxs, the structure will fail very soon and easily. so in the process of machining and production, cracks should be avoided carefully in pbxs parts. some important laws about klc of the three typical pbxs above changes with temperature have been obtained as follows : a
對三種具有代表性的高聚物粘結炸藥j1 、 j2和j3在常溫下的平面應變斷裂韌度進行了測試與研究,研究結果表明:相對于金屬及某些高分子材料而言,高聚物粘結炸藥的k _ ( ic )值很低,即高聚物粘結炸藥的抗裂紋擴展能力是極差的,一旦炸藥構件中產生了裂紋,炸藥構件將極易破壞,因此,在高聚物粘結炸藥構件的生產及加工過程中,應避免裂紋的產生。Abstract : in this paper, the characteristic of fracture development under gas explosion action is summerized, which is similar to the fracture development of structure under uniform distributed load. based on previous research, relative software is developed to simulate the dynamic procedure of fracture development. the fractal interpolation method is adopted and saves large amount of storage
